Reaction Steps

Bromo-acetyl bromide (0.0138 mol) was added slowly at 5° C. to a mixture of (±)-[2-amino-5-[(4-chlorophenyl)hydroxy(1-methyl-1H-imidazol-5-yl)methyl]phenyl](3-chlorophenyl)methanone (prepared as described in WO 97/21701) (0.0137 mol) in acetic acid (60 ml). The mixture was stirred for 15 min and poured out into EtOAc and NaOH 0.5N. The organic layer was separated, washed with water, dried (MgSO4), filtered and the solvent was evaporated till dryness, yielding 7.3 g (93%) of 2-bromo-N-[2-(3-chlorobenzoyl)-4-[(4-chlorophenyl)hydroxy(1-methyl-1H-imidazol-5-yl)methyl]phenyl]-acetamide (intermediate 4).
